Lena: You are sick.
Lex: Exactly. I'm dying.

Kelly: I picked the safe option. This isn't supposed to happen when you pick the safe option.
Alex: Kelly, look, no one could've predicted this was gonna happen. You made the best decision that you could for your brother, and Lena's drug wasn't ready then. But it's ready now. Now, look, I know you have 1,000 reasons to not trust Lena Luthor, but I'm not asking you to trust her. I'm asking that you to trust me.
Kelly: Let's do it.

Kelly: Plus, this is the 12th time that I have visited James in the hospital.
Alex: Wow.
Kelly: You know my brother, he was running off and diving into something dangerous. It was the way he coped when things got hard at home.
Alex: If you keep running than you don't have to stop and feel how much you're hurting.

Lex and Lena Luthor, teaming up to save Superman's best pal. What would mother think?

Lex Luthor

Besides, how can you pay your debt to society if you're already dead?
